  • "Thomas worked for me leading multiple high-priority, highly visible programs as part of a private equity carve out of a financial services business. Thomas's strong leadership, cross-functional engagement, communication, and problem solving skills ensured inter-program dependencies were accounted for and risks were identified and fully mitigated, ensuring each program delivered on-time, on-budget, and with quality."

    FCM – Mergers & Acquisitions

  • "I had the pleasure of working closely with Tom for over a year at Refinitiv when MSFT Services won the contract to help deliver a large scale data centre migration. Tom had a very collaborative manner and never backed away from dealing with conflict. Together we formed a fantastic team and navigated a tricky project through to conclusion. Despite the strangeness of 2020 to achieve such a great result is a testament to the way Tom helped create a vision for his team to follow."

    Senior Principal Account Delivery Executive at Microsoft

  • "As a Program Manager, Thomas was able to reach out to multiple internal and external stakeholders seamlessly. Thomas was known to have worked long hours and weekends to enable a smooth delivery of program milestones for the legal entity separation programs. With his focus, dedication and professionalism, Thomas will be an asset to a team. "

    Client Partner - Cognizant

  • "Caliber and collegiality are hallmarks of Thomas’ work. For approximately a year we worked together on an international compliance implementation. Thomas’ program management was informed by his deep understanding of the legal and practical requirements driving the effort, and his effectiveness was a significant factor in the productivity and successes of our team. Professionally and personally, it was a pleasure to collaborate with him. "

    Privacy Counsel – Thomson Reuters

  • "Tom is an excellent manager and great colleague. I worked with Tom on several Identity and Access Management programs during Merger and Acquisition activities over the course of 2 years and was particularly impressed with his ability to understand the resources required to complete a project and his proficiency in assembling the right people and skills to get it done. He is an excellent communicator and team leader; truly an asset for any program! "

    Technology Portfolio Management - FCM

  • "I had the pleasure of working with Thomas at Refinitiv, where he was leading the technical separation of the CISO platforms & services. It's without doubt that I say Thomas is one of the most progressive and driven program managers that I've worked with. Attention to detail, technically savvy, great stakeholder & ELT relationship management and gets the best out of his teams and direct reports.
    I have no hesitation in recommending Thomas to my network and believe him to be a credit to any organisation. "

    Technical Consultant & Delivery Lead

  • "I had the pleasure of working with Thomas for 2 years on a large scale separation program in Identity Access Management. The Active Directory separation was the most complex project I have ever been involved with. Thomas was the best Program Manager I have ever worked with. He always communicated well, was highly organized, and kept this program on track under immense pressure. If you need someone who can deliver under intense pressure and remove seemingly impossible barriers please consider Thomas.. "

    Cybersecurity Architect at Securian Financial

  • "I worked with Thomas for two years at Refinitiv, on the separation of Refinitiv's identity architecture. Thomas was committed, flexible and dependable throughout this programme - rising to the many challenges which arose, from late emerging requirements to resource and budgetary challenges and ever changing dependencies. Throughout this work Thomas built many strong relationships across the variety of stakeholder groups. I would welcome the opportunity to work with Thomas again! "
